FRED S. JEWET'I', 0F LACONIA, NEW HAMPSHIRE.

STRIP-FASTENER.

Application filed. September 19, 1914.

To all whom it may concern Be it known that I, FRED S. Jnwn'r'r, a citizen of the United States of America, residing at Laconia, in the county of Belknap and State of New Hampshire, have invented certain new and useful Improvements in Strip-Fasteners, of which the following is" a specification, reference being had to the accompanying drawings.

This invention relates to improvements in strip fasteners and particularly to improvements in fasteners for locking in place in a window-frame the strip commonly known as the parting bead; and an object of this invention is to provide a fastener or locking device of the character hereinbefore referred to which will be simple in construction, comparatively cheap in manufacture and eflicient, convenient and durable in operation and use.

In the drawings illustrating the principle of this invention and the best mode now known to me of applying that principle, Figure 1 is an elevation of so much of a window-frame as is necessary to illustrate my invention; Fig. 2 is an elevation of a framemember taken looking in the direction of the arrow A. Fig. 1; Fig. 3 is a section on the line BB of Fig. 2; Fig. 4 is a detail showing a part of the window-frame; Fig. 5 is a detail showing a portion of the parting head or strip; Fig. (i is an other View of the parting head or strip, the view being taken looking in the direction of the arrow C, Fig. 5; and Fig. 7 is a detail showing the key.

The parting bead or strip a lies between the window-sashes (not shown) and fits in the groove Z) formed in the inner edge of the window-frame or window-casing c. In the strip a there is mounted a transverse shaft (Z formed on its exterior with ringshaped teeth 6, which are so inclined as to permit the ready insertion of the shaft (Z but which prevent its withdrawal, as will be readily seen from the drawing (Fig. 3). The window-frame c is cut-away at f, and the wall f of this cut-away portion or recess is engaged by the ends of the head (Z of the lock-shaft d in the locking position of the latter (Fig. 2). The opposite end of the lock-shaft cl is formed with a pair of Specification of Letters Patent.

recesses or notches d in which may be engaged the lugs g projecting laterally from one end of the key h. By turning the lockshaft (Z by means of the key it, the head (1' may be turned out of locking engagement with the wall f, as will be readily seen from the dotted-line position in the drawing (Fig. 2); and, when the parting bead a is thus released, it may be readily withdrawn from the groove Z) formed in the windowframe 0.

In accordance with the provisions of the patent statutes I have described the principle of operation of my invention, together with the a paratus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is only representative and that the invention can be carried out by other means.

I claim:

1. The comb nation of a window-frame member formed with a groove: a parting bead mounted in said groove; and a rotary locking device for locking and unlocking said head to and from said window-frame member. sa d lock ng device be n formed with teeth inclined to the longitudinal axis thereof and arranged to pre ent movement of said device in one direct on along said axis. hen said device is turned.

2. The comb nat on of a window-frame member fo med with a groove: a parting be d mounted in said groo e and formed with an aperture: and a locking device for locking and unlocking said head to and from said window-frame ember. said locking de ce com rising a T-headed rotatable sh t d i en into sa d a erture and formed w th teeth inclined to the longitudinal axis of sa d shaft and arranged to prevent the lengthwise mo ement of said shaft in the direct on of the head thereof, when the sha t is turned.
